Chrysanthemum plant named ‘GEDI WO’

ABSTRACT

A new chrysanthemum plant variety producing white daisy-type flowers.

BACKGROUND OF THE INVENTION

The present invention is directed to a new and distinct variety of chrysanthemum botanically classified as Dendranthema grandiflora. The varietal denomination of the new chrysanthemum is ‘GEDI WO’.

The new variety is a natural occurring whole plant mutation of the variety ‘Ozenda’ (U.S. Plant Pat. No. 10,419), discovered as part of a breeding program October 1996 in Staden, Belgium. The new variety has been asexually reproduced by vegetative cuttings in Ventura County, Calif. and the distinguishing characteristics are retained through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

‘GEDI WO’ is a chrysanthemum plant that produces white daisy-type flowers with slight yellow tone in center.

COMPARISON WITH PARENTS

‘GEDI WO’ differs from its parent in having a white flower with a slight yellow tone in the center, whereas ‘Ozenda’ has light lavender ray florets.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph shows a typical specimen of the plant and flowers of the new variety with colors being as nearly true as possible with an illustration of this type.

DESCRIPTION OF THE PLANT

The following description of the new variety is of specimens grown in a greenhouse in Ventura County, Calif. in the month of April. ‘GEDI WO’ has not been observed under all possible environmental conditions. The phenotype may vary with variations in the environment such as temperature, light intensity, day length and cultural conditions. The color designations herein are from The Royal Horticultural Society Colour Chart except where general terms are used.

To produce a commercial product the plants may be pinched once about ten days after planting. It has been observed that longevity of individual blooms of ‘GEDI WO’ is about 28 days and the plant has a response time of about 7 weeks. No growth retardant has been applied in the specimens described. Useful growing conditions include night temperatures of about 18°-20° and day temperatures of about 20°-30°. The new variety is naturally blooming during late September to early October in Ventura County, Calif.
